Big Bore on 600

[IDAHO HOT SHOT]

Hearing a lot of jabber about the Big Bores working good. If I understand correctly, the 600 and 800 have the same bottom end. Does this mean that the, say Bikeman, RKT and Carl's BB's will work on a 6?

There not the same bottom end but the 600 iqr has the same bottom end as the 800.
